Ah yes, I remember the inconsistency / splitbrain issue race condition being discussed and demonstrated. Is migration from 1.3.x to 1.4.x transparent? Can I use the same pre-populated backing store from 1.3.x, with xattrs set as 1.3.x set them? Or is a backup/restore required? And if there is a problem, is the downgrade path clean (i.e. can I just put 1.3.x back if 1.4.x goes wrong for me)? Are there any changes to xattrs used/set that can cause compatibility problems? Thanks.
